kicker L7

i just got two kicker L7's and a hifonics bx 1500d. I was in town just showing ppl and some ppl were telling me that this dude with 2 15" audiopipe subs and a 2400 watt power acoustik amp hits harder than mine. I mean my system is pounding and sounds good to me. isnt audiopipe cheap crap and power acoustik. this kinda aggervates me what do u guys think.
